Hey there! As a supplier of Container Desiccant, I often get asked this question: "How much silica gel container desiccant is needed?" It's a crucial question because using the right amount can save you from a whole lot of trouble, like moisture damage during shipping. Let's dive right in and figure this out.
First off, you need to understand why we use silica gel in container desiccants. Silica gel is a super effective moisture absorber. It can soak up a large amount of water vapor, preventing condensation inside the shipping containers. Condensation can lead to all sorts of problems, such as rust on metal products, mold on wooden items, and damage to electronics. That's where our Container Desiccant Dry Packs come in handy.
Now, let's talk about how to calculate the amount of desiccant you need. There are a few factors to consider:
1. Container Size
The size of the container is a major factor. Obviously, a larger container will need more desiccant than a smaller one. For example, a 20 - foot container has a different moisture - absorbing requirement compared to a 40 - foot container. A 20 - foot container typically has a volume of around 33 cubic meters, while a 40 - foot container has a volume of about 67 cubic meters.
As a general rule of thumb, for a short - term shipment (less than 30 days) in a 20 - foot container, you might need around 10 - 15 units of standard - sized desiccant packs. For a 40 - foot container, you could need 20 - 30 units. But these are just rough estimates.
2. Cargo Type
Different types of cargo have different moisture sensitivities. Some goods are more prone to moisture damage than others. For instance, textiles, leather products, and food items are very sensitive to moisture. If you're shipping Clothes Moisture Absorber for Colthes, you'll want to make sure there's enough desiccant to keep the clothes dry and free from mold.
On the other hand, items like plastic products or metal parts that are well - coated are less sensitive. For moisture - sensitive cargo, you may need to increase the amount of desiccant by 20 - 30% compared to less sensitive goods.
3. Shipping Route
The shipping route also plays a big role. If your cargo is traveling through regions with high humidity, such as the tropics, you'll need more desiccant. The humidity in these areas can be as high as 80 - 90% or even more. In contrast, if the route is through dry regions, you can get away with using less desiccant.
Let's say you're shipping from a dry area like the Middle East to a humid area in Southeast Asia. You'll need to adjust the desiccant quantity accordingly. A good idea is to research the average humidity levels along the shipping route and factor that into your calculations.
4. Shipping Duration
The length of the shipping journey matters too. Longer shipments mean more time for moisture to accumulate inside the container. For a shipment that lasts more than 60 days, you'll probably need to double the amount of desiccant compared to a short - term shipment.
So, how do you put all these factors together to get an accurate estimate? Well, there's no one - size - fits - all formula, but here's a step - by - step approach:
- Determine the container volume: Measure or look up the volume of the container you're using.
- Assess the cargo sensitivity: Categorize your cargo as highly sensitive, moderately sensitive, or less sensitive to moisture.
- Research the shipping route: Find out the average humidity levels along the route.
- Consider the shipping duration: Decide whether it's a short - term, medium - term, or long - term shipment.
Based on these factors, you can then make an informed decision about the amount of desiccant. For example, if you're shipping moisture - sensitive cargo in a 40 - foot container on a long - term journey through a humid region, you might need 40 - 50 units of our Shipping Desiccant.
